Heating and air-conditioning system should have adjustability and stability in order to ensure the affect of providing cool and heat. On the basis of drawing theory and the water flowing regularity of pipe network, the mathematical model and constraint condition of water flow optimal regulation were provided and simplified for one water pump heating and air-conditioning system. By example, the node pressure method and steps of the water flow optimal regulation were introduced in order to provide the theory basis for the engineering application.
